🤖Prompt Engineering: Knowledge Bases (Just the Quotes)

"How can a cognitive system process environmental input and stored knowledge so as to benefit from experience? More specific versions of this question include the following: How can a system organize its experience so that it has some basis for action even in unfamiliar situations? How can a system determine that rules in its knowledge base are inadequate? How can it generate plausible new rules to replace the inadequate ones? How can it refine rules that are useful but non-optimal? How can it use metaphor and analogy to transfer information and procedures from one domain to another?" (John H Holland et al, "Induction: Processes Of Inference, Learning, And Discovery", 1986)

"Inference is the process of matching current facts from the domain space to the existing knowledge and inferring new facts. An inference process is a chain of matchings. The intermediate results obtained during the inference process are matched against the existing knowledge. The length of the chain is different. It depends on the knowledge base and on the inference method applied." (Nikola K Kasabov, "Foundations of Neural Networks, Fuzzy Systems, and Knowledge Engineering", 1996)

"Representation is the process of transforming existing problem knowledge to some of the known knowledge-engineering schemes in order to process it by applying knowledge-engineering methods. The result of the representation process is the problem knowledge base in a computer format." (Nikola K Kasabov, "Foundations of Neural Networks, Fuzzy Systems, and Knowledge Engineering", 1996)

"LLMs are trained on large volumes of data, which inherently provides them with an immense knowledge base and understanding of different languages. Yet, LLMs at their core are complex text completion engines. Since this knowledge and understanding of language is compressed in a very high-dimensional latent space. LLMs end up using these in a very fluid and intelligible way (which often leads to hallucinations). In order to guide LLMs to focus on specific topics or pieces of information to solve certain tasks, (for instance, question-answering from a given piece of text), it is important to provide contextual information explicitly. While most current generations of LLMs have extremely wide context windows, it is recommended to preprocess context into overlapping smaller chunks for better results, reduced latency, and so on. For similar reasons, it is also recommended to preprocess contextual information in clear and task-specific formats. This aspect of context preprocessing is extremely useful in Retrieval-Gugmented Generation (RAG) scenarios." (Joseph Babcock & Raghav Bali, "Generative AI with Python and PyTorch" 2nd. Ed., 2025)

"LLMs excel at understanding context and making associations among words, phrases, and concepts to provide relevant information based on the input query or prompt. While structured knowledge bases rely on humancurated data, LLMs can  automatically extract knowledge from unstructured text. When trained on diverse textual sources, they can process a vast amount of information without explicit human intervention. However, this also introduces a challenge, as the model can learn biased or incorrect information from the training data." (Abi Aryan, "LLMOps: Managing Large Language Models in Production", 2025)

"RAG is a framework that combines the strengths of traditional information retrieval systems with the generative capabilities of LLMs. In this setup, an LLM is augmented with a retrieval component that fetches relevant information from external data sources, such as knowledge bases or databases, to produce more accurate and contextually relevant responses. This method enhances the LLM’s output by grounding it in authoritative, up-to-date information." (Aldo Marzullo et al, "Graph Machine Learning" 2nd Ed., 2025)

"Semantic Kernel is a framework designed to simplify integrating LLMs into applications that require dynamic knowledge, reasoning, and state tracking. It’s particularly useful when you want to build complex, modular AI systems that can interact with external APIs, knowledge bases, or decision-making processes. Semantic Kernel focuses on building more flexible AI systems that can handle a variety of tasks beyond just generating text. It allows for modularity, enabling developers to easily combine different components - such as embeddings, prompt templates, and custom functions - in a cohesive manner." (Abi Aryan, "LLMOps: Managing Large Language Models in Production", 2025)

"Intelligent systems connect users to AI and ML to achieve meaningful objectives. An intelligent system is one in which intelligence evolves and improves over time, particularly when it improves by watching how users interact with the system.[...] The primary objective of the intelligent system is to support users in accomplishing complex tasks - not by replacing them, but by enhancing their decision-making capabilities. [...] An intelligent system must also have the ability to learn from user interactions and explicit feedback, as well as utilize contextual information. The system should contin-uously develop, use, and maintain an evolving knowledge base. This evolution is driven not only by data sources but also by ongoing interactions with users." (Alessandro Negro et al, "Knowledge Graphs and LLMs in Action", 2026)

"Misinformation is false or misleading information, and its generation by AI is particularly dangerous because of the aura of credibility these systems can project. In a RAG system, misinformation primarily arises from two failure points: Retrieval of inaccurate content from the knowledge base and fabrication or distortion by the large language model (LLM) during generation, even when given good context. The first line of defense is ensuring the integrity of the knowledge base. A RAG system is only as reliable as the documents it has access to. If non-credible, manipulated, or satirical sources are ingested, the system will retrieve and use them as fact. This makes rigorous data curation and source validation the most critical step in combating misinformation. The second line of defense is strengthening the connection between retrieval and generation to prevent the LLM from 'going off script'. The LLM, based on its pre-trained knowledge, might confidently generate an answer that contradicts the provided evidence or adds unsupported details – a phenomenon known as 'hallucination'. To mitigate this, thesystem must be designed to strictly adhere to the retrieved context." (Saloni Garg et al, "RAG Artificial Intelligence: Retrieval-Augmented Generation in Generative AI", 2026)

"The foundational form of RAG, often called naive RAG, follows a straightforward pattern. A pipeline retrieves supporting context from external sources such as enterprise documents, knowledge bases, or structured datasets and appends that information to the model’s prompt before inference. In the most common implementation, each document is converted into an embedding, a numerical representation of its semantic meaning, using either the same foundation model or a specialized embedding model. When a user submits a query, the system performs a vector similarity search to find documents whose embeddings most closely match the query’s vector representation, and the retrieved content is concatenated with the user query before being passed to the language model." (Bennie Haelen, "ML and Generative AI in the Data Lakehouse Building and Deploying AI Applications at Scale", 2026)

🤖Prompt Engineering: Failure (Just the Quotes)

"Agentic workflows break when the logic is messy - if, say, the plans don’t decompose or memory is poorly structured. However, infrastructure-level LLM applications introduce even more failure points and complexity. If the protocols don’t sync with each other, or the data flows start leaking, or the model boundaries are unclear... there are far too many failure points to count. While most people have been jumping on the bandwagon to adopt MCPs or A2A, very few are equipped to handle the LLMOps issues these tools introduce." (Abi Aryan, "LLMOps: Managing Large Language Models in Production", 2025)

"Data drift manifests in several distinct ways. Input drift typically shows up as an increase in adversarial or malformed queries that deviate from the original training or design expectations. This can stress the system’s robustness and degrade output quality. Retriever drift occurs when the relevance of the documents returned by retrieval components declines, even if the retrieval algorithms and configurations remain unchanged. Similarly, embedding drift arises when the vector representations used to compare semantic similarity become less effective, causing retrieval systems to fail despite stable system parameters." (Abi Aryan, "LLMOps: Managing Large Language Models in Production", 2025)

"LLM deployment failures often trace back not to the model itself, but to the prompts it receives. In production environments, prompts are rarely fixed, handcrafted snippets. Instead, they are dynamically generated, assembled from templates, and parameterized based on upstream data sources or evolving user state. This dynamism introduces complexity and variability that can subtly undermine the system’s performance if not carefully managed." (Abi Aryan, "LLMOps: Managing Large Language Models in Production", 2025)

"The simplest form of an agent is little more than a wrapped prompt. It takes an input, does some local reasoning, returns an output, and exits. There’s no memory, no iteration, no feedback loop. These are useful when the task is bounded, like generating a SQL query, converting a paragraph to a tweet, or answering a direct question. But single-step agents are brittle. They assume everything is known up front. They can’t handle surprises or partial failures. You’ll quickly outgrow them when tasks involve multiple actions or require state tracking." (Abi Aryan, "LLMOps: Managing Large Language Models in Production", 2025)

"If ethical lapses or AI failures occur, the impact on a business can be significant. Misinformation, biases, or harmful content generated by AI can lead to reputational damage, customer distrust, and potential regulatory scrutiny. The public relations fallout from an AI-driven error or ethical misstep can erode consumer confidence, resulting in lost revenue and lasting harm to brand image. Businesses, therefore, need to proactively address ethical considerations in AI implementation, not only to ensure compliance but also to protect and strengthen their reputation in a highly competitive, and increasingly transparent, marketplace." (Bennie Haelen, "ML and Generative AI in the Data Lakehouse Building and Deploying AI Applications at Scale", 2026)

"[...] KGs and LLMs can be the foundation for different types of reasoning, complementing each other in intelligent systems. We can use KGs for tasks that require precise, rule-based reasoning and explicit knowledge representation, and LLMs for tasks involving pattern recognition, context understanding, handling ambiguity or incomplete information, and reasoning about graph structures and their derived metrics. However, neither approach inherently possesses common-sense reasoning capabilities comparable to those of humans, and they often fail to make intuitive leaps or understand the implicit context that would be obvious to a person. These limitations underscore the importance of carefully considering the strengths and weaknesses of each approach when designing intelligent systems and potentially developing a powerful hybrid IAS."

"The promise of AI is its ability to process information objectively and at scale. However, this promise is fundamentally threatened by the twin challenges of bias and misinformation. AI systems are not born in a vacuum; they are created by humans and trained on data produced by humans. Consequently, they are prone to inheriting and even amplifying our prejudices, errors, and the systemic inequalities present in that data. In a RAG system, this risk is a two-fold problem: first in the retrieval of information, and second in the generation of a response based on that retrieval. A failure to address these issues doesn’t just lead to technically incorrect outputs; it can perpetuate social harm, erode public trust, and lead to the widespread dissemination of falsehoods. Therefore, understanding and mitigating bias and misinformation is not an optional add-on but a core requirement for any ethically deployed AI system."

🤖Prompt Engineering: Learning (Just the Quotes)

"There is a plethora of credible scenarios for achieving human-level intelligence in a machine. We will be able to evolve and train a system combining massively parallel neural nets with other paradigms to understand language and model knowledge, including the ability to read and understand written documents. Although the ability of today's computers to extract and learn knowledge from natural-language documents is quite limited, their abilities in this domain are improving rapidly. Computers will be able to read on their own, understanding and modeling what they have read, by the second decade of the twenty-first century. We can then have our computers read all of the world's literature books, magazines, scientific journals, and other available material. Ultimately, the machines will gather knowledge on their own by venturing into the physical world, drawing from the full spectrum of media and information services, and sharing knowledge with each other (which machines can do far more easily than their human creators)." (Ray Kurzweil, "The Age of Spiritual Machines: When Computers Exceed Human Intelligence", 1999)

"The no free lunch theorem for machine learning states that, averaged over all possible data generating distributions, every classification algorithm has the same error rate when classifying previously unobserved points. In other words, in some sense, no machine learning algorithm is universally any better than any other. The most sophisticated algorithm we can conceive of has the same average performance (over all possible tasks) as merely predicting that every point belongs to the same class. [...] the goal of machine learning research is not to seek a universal learning algorithm or the absolute best learning algorithm. Instead, our goal is to understand what kinds of distributions are relevant to the 'real world' that an AI agent experiences, and what kinds of machine learning algorithms perform well on data drawn from the kinds of data generating distributions we care about." (Ian Goodfellow et al, "Deep Learning", 2015)

"Self-attention, sometimes called intra-attention is an attention mechanism relating different positions of a single sequence in order to compute a representation of the sequence. Self-attention has been used successfully in a variety of tasks including reading comprehension, abstractive summarization, textual entailment and learning task-independent sentence representations.  End-to-end memory networks are based on a recurrent attention mechanism instead of sequence-aligned recurrence and have been shown to perform well on simple-language question answering and language modeling tasks. To the best of our knowledge, however, the Transformer is the first transduction model relying entirely on self-attention to compute representations of its input and output without using sequence-aligned RNNs or convolution." (Ashish Vaswani et al, "Attention Is All You Need", 2017)

"[...] building an effective LLM-based application can require more than just plugging in a pre-trained model and retrieving results - what if we want to parse them for a better user experience? We might also want to lean on the learnings of massively large language models to help complete the loop and create a useful end-to-end LLM-based application. This is where prompt engineering comes into the picture." (Sinan Ozdemir, "Quick Start Guide to Large Language Models: Strategies and Best Practices for Using ChatGPT and Other LLMs", 2024) 

"Language modeling is a subfield of NLP that involves the creation of statistical/deep learning models for predicting the likelihood of a sequence of tokens in a specified vocabulary (a limited and known set of tokens). There are generally two kinds of language modeling tasks out there: autoencoding tasks and autoregressive tasks." (Sinan Ozdemir, "Quick Start Guide to Large Language Models: Strategies and Best Practices for Using ChatGPT and Other LLMs", 2024)

"The idea behind transfer learning is that the pre-trained model has already learned a lot of information about the language and relationships between words, and this information can be used as a starting point to improve performance on a new task. Transfer learning allows LLMs to be fine-tuned for specific tasks with much smaller amounts of task-specific data than would be required if the model were trained from scratch. This greatly reduces the amount of time and resources needed to train LLMs." (Sinan Ozdemir, "Quick Start Guide to Large Language Models: Strategies and Best Practices for Using ChatGPT and Other LLMs", 2024)

"Transfer learning is a technique used in machine learning to leverage the knowledge gained from one task to improve performance on another related task. Transfer learning for LLMs involves taking an LLM that has been pre-trained on one corpus of text data and then fine-tuning it for a specific 'downstream' task, such as text classification or text generation, by updating themodel’s parameters with task-specific data." (Sinan Ozdemir, "Quick Start Guide to Large Language Models: Strategies and Best Practices for Using ChatGPT and Other LLMs", 2024)

"As with many other deep learning-based approaches, another major challenge is in interpretability. While knowledge graphs provide a structured and transparent way to store relationships, LLMs operate as a black box, making it difficult to understand how specific outputs are generated. [...] Data alignment is also a key issue, as structured knowledge graphs and unstructured text data must be carefully preprocessed to ensure consistency.  Differences in data formats, ontology mismatches, and information redundancy can create inefficiencies when integrating these two paradigms. Developing robust pipelines that seamlessly connect graph-based insights with LLM-generated text remains an open challenge." (Aldo Marzullo et al, "Graph Machine Learning" 2nd Ed., 2025)

"Generative AI for coding and language tools is based on the LLM concept. A large language model is a type of neural network that processes and generates text in a humanlike way. It does this by being trained on a massive dataset of text, which allows it to learn human language patterns, as described previously. It lets LLMs translate, write, and answer questions with text. LLMs can contain natural language, source code, and  more." (Jeremy C Morgan, "Coding with AI: Examples in Python", 2025)

"LLMs excel at understanding context and making associations among words, phrases, and concepts to provide relevant information based on the input query or prompt.

"Transformers are complex models built like LEGO blocks using multiple smart and specialized components. [...] Briefly, a vanilla transformer model consists of separate stacks of encoders and decoders. Each encoder block includes multi-head self-attention, enabling the model to capture relationships between tokens regardless of their positions. Residual connections help maintain gradient flow, preventing the vanishing gradient problem. Layer normalization ensures training stability, and feed-forward layers introduce non-linearity and learn complex token interactions. Decoder blocks contain the same components but also include an encoder-decoder attention mechanism to incorporate context from the encoder. The model uses embedding layers to convert tokens into a continuous latent space for contextual learning and positional encoding to preserve the order of tokens in the sequence." (Joseph Babcock & Raghav Bali, "Generative AI with Python and PyTorch" 2nd. Ed., 2025)

"With MCP, a model no longer has to guess what’s possible. Instead, it can discover tools, query data sources, and select prompts - all in real time, all through a shared protocol. This means a model doesn’t just generate responses; it acts, it calls tools, it gathers context, and it learns how to interact with the outside world in a modular, controlled way." (Abi Aryan, "LLMOps: Managing Large Language Models in Production", 2025)

"Generative AI has a lot of problems because it needs a lot of data to work. Generative models like GPT and GANs need a lot of training data to learn patterns and make good outputs. This data dependency can cause problems like overfitting, which happens when the model does well on training data but doesn’t work well with new, unseen data. Also, the quality of the content that is generated is directly related to the diversity and representativeness of the training data. This means that biased or incomplete datasets can lead to outputs that are wrong or unfair." (Saloni Garg et al, "RAG Artificial Intelligence: Retrieval-Augmented Generation in Generative AI", 2026)

"In RAG methods, the AI model itself doesn’t actually 'remember' or learn the proprietary data directly. Instead, the proprietary data are stored separately in what’s called a vector database. When the model is asked a question, it first performs a quick search of the proprietary database, finds relevant pieces of information, and then uses these to generate its response. The model’s core parameters remain entirely unchanged and are never updated with this private data. In this sense, the model hasn’t learned or 'seen' your proprietary data in its internal parameters, it only temporarily consults it as a reference to formulate an answer." (Alan Watkins & G C Cooke, "Smarter than You Winning in Business with Superintelligent AI", 2026

"Intelligent systems connect users to AI and ML to achieve meaningful objectives. An intelligent system is one in which intelligence evolves and improves over time, particularly when it improves by watching how users interact with the system.[...] The primary objective of the intelligent system is to support users in accomplishing complex tasks - not by replacing them, but by enhancing their decision-making capabilities.

"LangGraph handles the perception, reasoning, and action flow while maintaining memory and context across tasks. In this sense, it functions as both the development environment and the orchestration layer - coordinating the steps of perception, reasoning, and action while managing connections to external systems. Underneath this, emerging standards like MCP ensure that agents can connect securely and consistently to tools and data sources, making agentic architectures portable and scalable across platforms. Taken together, the orchestration layer and emerging interoperability standards like MCP form the foundation for scalable agentic AI. They make it possible for agents to perceive, reason, act, and learn in coordinated ways across complex environments, translating autonomous intelligence into practical, enterprise-grade capability." (Fern Halper, "Data Makes the World Go 'Round", 2026)

"RAG models offer several advantages over standard generative models, addressing many of their limitations. Traditional generative models, like GPT, rely solely on patterns learned during training, which can lead to issues such as factual inaccuracies, model hallucinations, and lack of contextual relevance. These models generate content based on pre-existing knowledge, often without the ability to verify or update the information, making them less reliable for tasks requiring high accuracy. In contrast, RAG models integrate retrieval mechanisms that allow them to access external knowledge sources in real time. This ensures that the generated content is grounded in verified data, significantly improving factual consistency and relevance. For example, while a standard generative model might produce a plausible but incorrect answer to a factual question, a RAG model can retrieve and incorporate accurate information from a trusted source, reducing errors." (Saloni Garg et al, "RAG Artificial Intelligence: Retrieval-Augmented Generation in Generative AI", 2026)

"Retrieval mechanisms are essential for addressing some of the key limitations of traditional generative AI models, such as factual inaccuracies, lack of context awareness, and model hallucinations. While generative models excel at creating coherent and fluent content, they often struggle to produce outputs that are factually correct or contextually relevant. This is because these models rely solely on patterns learned during training, without access to real-time or external information. For example, a generative model might generate a plausible-sounding but incorrect answer to a factual question, as it cannot verify the accuracy of its response."

"The art of mega-prompts spanning multiple written pages and looking like essays has become commonplace for complex tasks when building applications to get things `just right'. Unfortunately, they bring with them lots of issues: errors, portability, complexity, and more. The GenAI world didn’t plan for mega-prompts. They have simply evolved into what they’ve become today because practitioners kept wanting to do more and more complex things, and their only way to express those intents was with a prompt. But step back and look at some of these prompts [...] Lurking just below the surface are a bunch of classical computing concepts like data, programming instructions, control flows, memory, and stora - all the components typically associated with classical computing elements." (Rob Thomas et al, "AI Value Creators: Beyond the Generative AI User Mindset", 2025)

"The same difficulties that characterize training deep feedforward networks also apply to RNNs; gradients tend to die out over long distances using traditional activation functions (or explode if the gradients become greater than 1). However, unlike feedforward networks, RNNs aren’t trained with traditional backpropagation, but rather a variant known as Backpropagation through Time (BPTT): the network is unrolled, as before, and backpropagation is used, averaging over errors at each time point (since an 'output', the hidden state, occurs at each step). Also, in the case of RNNs, we run into the problem that the network has a very short memory; it only incorporates information from the most recent unit before the current one and has trouble maintaining long-range context. For applications such as translation, this is clearly a problem, as the interpretation of a word at the end of a sentence may depend on terms near the beginning, not just those directly preceding it."

"[...] RAG models excel in dynamic environments where information changes frequently, such as news generation or customer support. Standard generative models, constrained by their training data, may provide outdated or irrelevant responses. RAG, however, can pull the latest information, ensuring up-to-date and contextually appropriate outputs.

"With autonomous agents there is the risk that they can take action that isn’t governed. These systems introduce autonomy, interdependence between agents, and possibly emergent behavior. [...] Because agents act autonomously, a single misconfigured or misaligned agent can propagate errors at scale. In multiagent environments, one faulty output can trigger many downstream mistakes. Other risks include tool misuse, conflicting goals among agents (and other interoperability issues), and operational opacity, when teams cannot easily determine which agent took which action or why. Governance must extend to agent registration, version control, permissioning, and simulation testing before deployment. Likewise, accountability may also blur. If an agent takes a dangerous action, who is responsible? There are, of course, cybersecurity risks as agents pose a new attack surface."  (Fern Halper, "Data Makes the World Go 'Round", 2026)

"As the tech industry moves from non-generative models to generative models, it is shifting away from feature engineering, or creating features to model the data and experimenting with different hyperparameters to optimize performance. Generative models, and specifically LLMs, do not require feature engineering. Today, the core requirements are usually prompt engineering or building a RAG pipeline - skills that lie within the domain of AI engineers." (Abi Aryan, "LLMOps: Managing Large Language Models in Production", 2025)

"Context is crucial for how language models understand and generate code. The model processes your input by analyzing relationships between different parts of the code and documentation to determine meaning and intent. [...] The model evaluates context by calculating mathematical relationships between elements in your input. However, it may miss important domain knowledge, coding standards, or architectural patterns that experienced developers understand implicitly." (Jeremy C Morgan, "Coding with AI: Examples in Python", 2025)

"Despite their impressive capabilities, LLMs are not without limitations. One of the most significant challenges is the problem of hallucination, where an LLM generates factually incorrect or misleading information that appears plausible. This is particularly problematic in domains requiring high factual accuracy, such as healthcare, finance, and legal applications. To mitigate hallucinations and enhance the reliability of LLM outputs,  Retrieval-Augmented Generation (RAG) has emerged as a powerful technique. RAG works by dynamically retrieving relevant information from an external knowledge source (such as a knowledge graph) at inference time, rather than just relying on pre-trained knowledge. This approach ensures that the model has access to up-to-date and accurate data, grounding answers in verified information rather than generating content purely from its internal representations." (Aldo Marzullo et al, "Graph Machine Learning" 2nd Ed., 2025)

"In prompt engineering, we customize the prompts or questions we give the model to get more accurate or insightful responses. The way a prompt is structured has a massive impact on how well a model understands the task at hand and, ultimately, how well it performs. Given LLMs’ versatility, prompt engineering has become an important skill for getting the most out of these models across different domains and tasks. The key is to understand how different prompt structures lead to different model behaviors. There are various strategies - ranging from simple one-shot prompting to more complex techniques like chain-of-thought prompting - that can significantly improve the effectiveness of LLMs." (Abi Aryan, "LLMOps: Managing Large Language Models in Production", 2025)

 "There are three techniques for model domain adaptation: prompt engineering, RAG, and fine-tuning. Strictly speaking, RAG is a form of dynamic prompt engineering where developers use a retrieval system to add content to an existing prompt, but RAG systems are used so often that it’s worth discussing them separately. One critical difference with fine-tuning is that you must have access to the model’s weights, information that is usually not available with cloud-based, proprietary LLMs." (Abi Aryan, "LLMOps: Managing Large Language Models in Production", 2025)

"Generative artificial intelligence (GenAI), powered by large language models (LLMs) like Google’s Gemini and OpenAI’s GPT, has transformed how we work and live, revolutionizing business after business. Despite this success, generative AI falls short in domains where specific domain knowledge, high accuracy, and explainability are essential. And it has other significant limitations, including hallucinations and a lack of context and relations. This is where knowledge graphs (KGs) come in, provid-ing contextual information - such as experiences, environmental characteristics, cultural aspects, and social normsneeded to build the 'third wave of AI' for mission-critical applications." (Alessandro Negro et al, "Knowledge Graphs and LLMs in Action", 2026)

"KGs are sophisticated graph structures that represent real-world entities (people, places, diseases, proteins), define meaningful connections between them, and provide context. KGs provide structured, explainable knowledge representation but are challenging to build and query; LLMs offer natural language processing capabilities but suffer from hallucinations, stale information, and a lack of domain-specific grounding. Together, they are a 'killer combination': LLMs can extract entities and relationships from unstructured text to build KGs more efficiently, providing more autonomous and powerful graph querying and analysis. Meanwhile, KGs provide reliable, up-to-date domain knowledge to ground LLM responses and prevent hallucinations." (Alessandro Negro et al, "Knowledge Graphs and LLMs in Action", 2026)

"RAG is a paradigm that combines the strengths of LLMs with the rich, often unstructured data stored in a lakehouse. Rather than asking an LLM to generate responses purely from its internal parameters and training data, where knowledge can be outdated or incomplete, RAG systems first retrieve relevant documents, records, or data slices from your lakehouse and then feed those pieces into the model as context for its generative step. The result is an AI that can speak confidently about the latest reports, proprietary datasets, or domain-specific knowledge you have stored without having to retrain the model each time your data changes." (Bennie Haelen, "ML and Generative AI in the Data Lakehouse Building and Deploying AI Applications at Scale", 2026)

"Traditional paradigms build systems for specific purposes with structured, homogeneous databases. This approach works for tailored needs but is impractical for complex domains that need to adapt to user characteristics and integrate heterogeneous data. KGs capture connections, enabling relationship discovery through graph pattern matching and traversal. Both the Resource Description Framework (RDF) and Labeled Property Graphs (LPGs) provide machine-readable formats that humans can interpret. KGs emphasize rich, meaningful data representations usable by both humans and machines, enabling a paradigm shift where intelligent behavior is encoded in a unique source of truth." (Alessandro Negro et al, "Knowledge Graphs and LLMs in Action", 2026)

🤖Prompt Engineering: Retrieval Augmented Generation [RAG] (Just the Quotes)

"As the tech industry moves from non-generative models to generative models, it is shifting away from feature engineering, or creating features to model the data and experimenting with different hyperparameters to optimize performance. Generative models, and specifically LLMs, do not require feature engineering. Today, the core requirements are usually prompt engineering or building a RAG pipeline - skills that lie within the domain of AI engineers." (Abi Aryan, "LLMOps: Managing Large Language Models in Production", 2025)

"Despite their impressive capabilities, LLMs are not without limitations. One of the most significant challenges is the problem of hallucination, where an LLM generates factually incorrect or misleading information that appears plausible. This is particularly problematic in domains requiring high factual accuracy, such as healthcare, finance, and legal applications. To mitigate hallucinations and enhance the reliability of LLM outputs,  Retrieval-Augmented Generation (RAG) has emerged as a powerful technique. RAG works by dynamically retrieving relevant information from an external knowledge source (such as a knowledge graph) at inference time, rather than just relying on pre-trained knowledge. This approach ensures that the model has access to up-to-date and accurate data, grounding answers in verified information rather than generating content purely from its internal representations." (Aldo Marzullo et al, "Graph Machine Learning" 2nd Ed., 2025)

 "There are three techniques for model domain adaptation: prompt engineering, RAG, and fine-tuning. Strictly speaking, RAG is a form of dynamic prompt engineering where developers use a retrieval system to add content to an existing prompt, but RAG systems are used so often that it’s worth discussing them separately. One critical difference with fine-tuning is that you must have access to the model’s weights, information that is usually not available with cloud-based, proprietary LLMs." (Abi Aryan, "LLMOps: Managing Large Language Models in Production", 2025)

"RAG is a framework that combines the strengths of traditional information retrieval systems with the generative capabilities of LLMs. In this setup, an LLM is augmented with a retrieval component that fetches relevant information from external data sources, such as knowledge bases or databases, to produce more accurate and contextually relevant responses. This method enhances the LLM’s output by grounding it in authoritative, up-to-date information." (Aldo Marzullo et al, "Graph Machine Learning" 2nd Ed., 2025)

"Vector databases are designed to store and index high-dimensional embeddings - dense numeric vectors that capture the semantic meaning of text, images, audio, or other content. Instead of looking for exact matches, they use approximate nearest neighbor (ANN) algorithms to return the items whose vectors lie closest to a query vector in that multidimensional space. This makes them the engine behind semantic search, recommendation systems, image-or-audio similarity matching, and retrieval augmented generation (RAG) pipelines that supply LLM prompts with relevant context in milliseconds." (Abi Aryan, "LLMOps: Managing Large Language Models in Production", 2025)

"In RAG methods, the AI model itself doesn’t actually 'remember' or learn the proprietary data directly. Instead, the proprietary data are stored separately in what’s called a vector database. When the model is asked a question, it first performs a quick search of the proprietary database, finds relevant pieces of information, and then uses these to generate its response. The model’s core parameters remain entirely unchanged and are never updated with this private data. In this sense, the model hasn’t learned or 'seen' your proprietary data in its internal parameters, it only temporarily consults it as a reference to formulate an answer." (Alan Watkins & G C Cooke, "Smarter than You Winning in Business with Superintelligent AI", 2026)

"Misinformation is false or misleading information, and its generation by AI is particularly dangerous because of the aura of credibility these systems can project. In a RAG system, misinformation primarily arises from two failure points: Retrieval of inaccurate content from the knowledge base and fabrication or distortion by the large language model (LLM) during generation, even when given good context. The first line of defense is ensuring the integrity of the knowledge base. A RAG system is only as reliable as the documents it has access to. If non-credible, manipulated, or satirical sources are ingested, the system will retrieve and use them as fact. This makes rigorous data curation and source validation the most critical step in combating misinformation. The second line of defense is strengthening the connection between retrieval and generation to prevent the LLM from 'going off script'. The LLM, based on its pre-trained knowledge, might confidently generate an answer that contradicts the provided evidence or adds unsupported details – a phenomenon known as 'hallucination'. To mitigate this, the system must be designed to strictly adhere to the retrieved context." (Saloni Garg et al, "RAG Artificial Intelligence: Retrieval-Augmented Generation in Generative AI", 2026)

"RAG applications must be built with semantics, metadata, and governance in mind. The retrieved information must be high-quality, secure, and appropriate for the user’s role. Equally important is monitoring and management: checking whether source data has changed, ensuring vector stores remain accurate, and watching for hallucinations or data leakage. Organizations are definitely starting to experiment with RAG models today; some are putting them into production applications. Some believe that using RAG helps mitigate hallucinations because it is grounded in trusted organizational data." (Fern Halper, "Data Makes the World Go 'Round", 2026)

"RAG is a framework that combines the strengths of generative models and retrieval mechanisms to produce more accurate and contextually relevant outputs. The process begins with an input query or prompt, which is used to retrieve relevant information from an external knowledge source, such as a database, document repository, or the internet. This retrieval step ensures that the model has access to up-to-date and verified information, addressing the limitations of traditional generative models that rely solely on pretrained knowledge." (Saloni Garg et al, "RAG Artificial Intelligence: Retrieval-Augmented Generation in Generative AI", 2026)

"RAG is a paradigm that combines the strengths of LLMs with the rich, often unstructured data stored in a lakehouse. Rather than asking an LLM to generate responses purely from its internal parameters and training data, where knowledge can be outdated or incomplete, RAG systems first retrieve relevant documents, records, or data slices from your lakehouse and then feed those pieces into the model as context for its generative step. The result is an AI that can speak confidently about the latest reports, proprietary datasets, or domain-specific knowledge you have stored without having to retrain the model each time your data changes." (Bennie Haelen, "ML and Generative AI in the Data Lakehouse Building and Deploying AI Applications at Scale", 2026)

"RAG models offer several advantages over standard generative models, addressing many of their limitations. Traditional generative models, like GPT, rely solely on patterns learned during training, which can lead to issues such as factual inaccuracies, model hallucinations, and lack of contextual relevance. These models generate content based on pre-existing knowledge, often without the ability to verify or update the information, making them less reliable for tasks requiring high accuracy. In contrast, RAG models integrate retrieval mechanisms that allow them to access external knowledge sources in real time. This ensures that the generated content is grounded in verified data, significantly improving factual consistency and relevance. For example, while a standard generative model might produce a plausible but incorrect answer to a factual question, a RAG model can retrieve and incorporate accurate information from a trusted source, reducing errors." (Saloni Garg et al, "RAG Artificial Intelligence: Retrieval-Augmented Generation in Generative AI", 2026)

"The foundational form of RAG, often called naive RAG, follows a straightforward pattern. A pipeline retrieves supporting context from external sources such as enterprise documents, knowledge bases, or structured datasets and appends that information to the model’s prompt before inference. In the most common implementation, each document is converted into an embedding, a numerical representation of its semantic meaning, using either the same foundation model or a specialized embedding model. When a user submits a query, the system performs a vector similarity search to find documents whose embeddings most closely match the query’s vector representation, and the retrieved content is concatenated with the user query before being passed to the language model." (Bennie Haelen, "ML and Generative AI in the Data Lakehouse Building and Deploying AI Applications at Scale", 2026)

"The promise of AI is its ability to process information objectively and at scale. However, this promise is fundamentally threatened by the twin challenges of bias and misinformation. AI systems are not born in a vacuum; they are created by humans and trained on data produced by humans. Consequently, they are prone to inheriting and even amplifying our prejudices, errors, and the systemic inequalities present in that data. In a RAG system, this risk is a two-fold problem: first in the retrieval of information, and second in the generation of a response based on that retrieval. A failure to address these issues doesn’t just lead to technically incorrect outputs; it can perpetuate social harm, erode public trust, and lead to the widespread dissemination of falsehoods. Therefore, understanding and mitigating bias and misinformation is not an optional add-on but a core requirement for any ethically deployed AI system." (Saloni Garg et al, "RAG Artificial Intelligence: Retrieval-Augmented Generation in Generative AI", 2026)

"Traditional NLP systems rely on static, pretrained knowledge embedded within their parameters, limiting their responses to information available during training. In contrast, RAG systems dynamically access external knowledge bases in real time, enabling them to provide up-to-date and contextually relevant answers. This fundamental distinction leads to key differences in architecture, performance, and adaptability." (Saloni Garg et al, "RAG Artificial Intelligence: Retrieval-Augmented Generation in Generative AI", 2026)

"The foundational premise of RAG is that the most effective way to reduce hallucinations is to provide the LLM with the correct, explicit information needed to answer a query, thereby minimizing its need to rely on fallible parametric knowledge. Therefore, the quality, relevance, and accuracy of the retrieval step are the most significant factors in determining the truthfulness of the final output. Better retrieval is the most powerful antidote to hallucination. If the retriever fails to find the correct information, the generator is essentially left to guess, making hallucinations almost inevitable. The goal is to create a tight, unambiguous link between the user’s question and the evidence in the knowledge base." (Saloni Garg et al, "RAG Artificial Intelligence: Retrieval-Augmented Generation in Generative AI", 2026)

"The power of RAG systems stems from their ability to access and process vast amounts of data. However, this very capability introduces significant risks regarding the privacy of individuals and the security of sensitive information. Unlike a simple chatbot, a RAG system often has access to proprietary corporate data, internal documentation, and potentially personal user information within its knowledge base. A data breach or misuse of this information can lead to severe financial, legal, and reputational damage. Furthermore, a global patchwork of stringent regulations now governs how personal data must be handled, making compliance a central pillar of AI system design, not an afterthought. Ethical deployment requires an architecture built on privacy by design and by default, ensuring user trust is maintained through robust technical and procedural safeguards."

Prompt Engineering Series

Prompt: "write a post of 600 words on the impact of consistent and high‑quality training data on AI"

Introduction

Over the past several years, Microsoft, Google, Amazon, Meta, and other technology giants have invested unprecedented sums into Artificial Intelligence (AI). They are building GPU superclusters, expanding datacenter capacity, training frontier‑scale models, and subsidizing AI usage across consumer and enterprise products. These investments are justified by the belief that AI will become the next foundational computing platform - driving productivity, reshaping cloud economics, and unlocking new trillion‑dollar markets.

But massive investment comes with massive risk. If AI adoption, monetization, and real‑world impact fail to keep pace with spending, the industry could find itself in a classic economic bubble: inflated expectations, unsustainable burn rates, and a painful correction. The key question is how long vendors can sustain this trajectory before the imbalance becomes too large to ignore.

1. Financial Strength Buys Time - But Not Unlimited Time

Microsoft, Google, and Amazon have enormous financial buffers. Microsoft alone generates more than $80 billion in annual operating income, giving it the ability to absorb AI losses for several years. This financial resilience allows vendors to continue investing even when short‑term returns are modest.

However, financial strength is not infinite. If AI revenue fails to scale, vendors will eventually face pressure to reduce capital expenditure. The sustainability window is long - 3 to 7 years - but not indefinite. This is the core of financial runway.

2. Investor Expectations Are the Real Timer

Investors currently tolerate massive AI losses because they believe in long‑term returns. As long as vendors show:

• rapid adoption
• credible monetization pathways
• strong ecosystem growth
• increasing enterprise integration
• the market remains patient. 

But if expectations diverge too far from reality, investor sentiment can shift quickly.

A bubble forms when expectations grow faster than fundamentals. If AI revenue plateaus while spending accelerates, investors will demand:

• reduced spending
• clearer profitability timelines
• more conservative guidance

This is the dynamic of expectation inflation.

3. Infrastructure Expansion Has Natural Limits

Even if vendors wanted to sustain massive spending indefinitely, physical constraints prevent it. Datacenters require land, power, cooling, and specialized hardware. Supply chains for GPUs and networking fabric are already strained.

These constraints slow the pace of expansion and act as a natural brake on bubble formation. Vendors cannot overspend infinitely because the infrastructure simply cannot scale infinitely. This is the logic behind infrastructure bottlenecks.

4. The Bubble Threshold: When Costs Outrun Value

An economic bubble emerges when the perceived future value of AI becomes disconnected from its actual economic output. Warning signs include:

• AI revenue growing slower than AI costs
• enterprises reducing or delaying adoption
• vendors subsidizing usage at unsustainable levels
• datacenter expansion outpacing utilization
• investors questioning long‑term profitability

If these trends intensify, the bubble becomes visible. Most analysts believe the industry has 3–5 years before this risk becomes acute.

5. What Happens If the Bubble Pops?

If AI fails to meet expectations, vendors would be forced to:

• cut capital expenditure
• slow frontier‑model training
• consolidate datacenter expansion
• shift focus to smaller, more efficient models
• prioritize profitable cloud workloads

The industry would not collapse - but it would undergo a painful correction.

Conclusion

Microsoft and other vendors can sustain massive AI investments for several years thanks to strong balance sheets, strategic necessity, and investor patience. But if AI fails to deliver the expected economic transformation, the industry risks drifting into an economic bubble where spending outpaces value creation.

The sustainability window is long - but not limitless. Without measurable returns, vendors will eventually face pressure to reduce spending, recalibrate expectations, and shift toward more efficient AI strategies. The next few years will determine whether AI becomes the next great computing platform - or the next great over‑investment cycle.

Prompt Engineering Series

Prompt: "write a post of 600 words and explain what will happen if the AI investments made by Microsoft and other vendors don't meet the expectations"

Introduction

Over the past five years, Microsoft, Google, Amazon, Meta, and other tech giants have poured unprecedented amounts of capital into Artificial Intelligence (AI) . They have built GPU superclusters, expanded datacenter footprints, acquired strategic partners, and trained frontier‑scale models that cost hundreds of millions per run. These investments are justified by the belief that AI will become the next foundational computing platform - bigger than cloud, bigger than mobile, and potentially bigger than the internet itself.

But what if this future doesn’t materialize as expected? What if adoption slows, monetization lags, or the technology fails to deliver the transformative productivity gains vendors promise? The consequences would be profound, reshaping corporate strategy, investor sentiment, and the trajectory of the entire industry.

1. Financial Pressure Would Force a Strategic Reset

If AI revenues fail to scale, the first impact would be financial compression. AI infrastructure is extraordinarily expensive, and vendors currently tolerate losses because they expect future dominance. Without that payoff, companies would be forced to:

• Reduce capital expenditure on datacenters
• Slow GPU procurement
• Consolidate or cancel frontier‑model training cycles
• Shift investment back toward profitable core businesses

This is the classic pattern of strategic retrenchment - a pivot from aggressive expansion to defensive cost control.

2. Cloud Growth Would Stall

AI is the engine driving the next wave of cloud adoption. If AI underperforms, cloud hyperscalers would lose a major growth vector. Azure, AWS, and Google Cloud rely on AI workloads to justify new datacenter regions and premium compute tiers.

A slowdown would mean:

• Lower utilization of new datacenters
• Reduced demand for high‑margin GPU instances
• Pressure on cloud revenue forecasts

This would be especially painful for Microsoft, whose AI strategy is tightly integrated with Azure’s long‑term growth.

3. Investor Confidence Would Erode

Right now, investors tolerate massive AI losses because they believe in long‑term returns. If expectations are not met, that tolerance evaporates. The market would demand:

• Clear profitability timelines
• Reduced spending
• More conservative guidance
• A shift toward predictable revenue streams

This is the dynamic of market correction - a recalibration of expectations that forces vendors to justify every dollar spent.

4. Competitive Dynamics Would Shift

If frontier‑scale AI fails to deliver, the competitive landscape changes dramatically. Companies that bet heavily on large models would lose strategic leverage, while those investing in smaller, specialized, or hybrid approaches could gain ground.

Meta’s open‑source strategy, for example, would look far more attractive if massive proprietary models fail to produce returns. Smaller vendors could also rise by focusing on niche, cost‑efficient AI rather than universal intelligence.

This is the logic behind competitive inversion.

5. Enterprise Adoption Would Slow

Enterprises currently experiment with AI because vendors subsidize usage. If investments fail, subsidies shrink, prices rise, and adoption slows. Companies would revert to:

• Traditional automation
• Classical machine learning
• Rule‑based systems
• Domain‑specific analytics

AI would remain useful - but not transformative.

Conclusion

If AI investments fail to meet expectations, the consequences would be severe but not catastrophic. Vendors would survive, but the industry would undergo a major strategic reset. Spending would decline, cloud growth would slow, investor pressure would intensify, and the competitive landscape would shift toward smaller, more efficient models.

AI would still matter - but it would no longer be the defining platform of the next era. The companies that adapt fastest to this reality would shape the future, whether or not frontier‑scale AI delivers on its promise

Prompt Engineering Series

Prompt: "write a post of 600 words and explain how long the AI investments can be sustained by Microsoft and other vendors as they generate huge losses"

Introduction

The Artificial Intelligence (AI) boom has triggered one of the largest capital outlays in the history of technology. Microsoft, Google, Amazon, Meta, and others are spending tens of billions of dollars annually on GPUs, data centers, research partnerships, and frontier‑model development. These investments generate enormous short‑term losses, raising a critical question: How long can this level of spending be sustained?

The answer depends on three forces: financial capacity, strategic necessity, and market expectations. Together, they determine how long vendors can tolerate losses before AI must begin paying for itself.

1. Financial Capacity: The Balance Sheet Determines the Burn Rate

Microsoft, Google, and Amazon are not startups - they are trillion‑dollar companies with deep cash reserves, diversified revenue streams, and high creditworthiness. This gives them the ability to sustain losses for years, not months.

Microsoft alone generates more than $80 billion in annual operating income, which acts as a buffer for AI losses. As long as core businesses - cloud, enterprise software, Windows, Office - continue to perform, Microsoft can redirect profits to subsidize AI expansion.

This is why financial resilience is the first determinant of sustainability.

2. Strategic Necessity: AI Is Not Optional

AI is the next computing platform. Vendors know that whoever controls the dominant AI ecosystem will shape:

• cloud workloads
• enterprise automation
• developer tooling
• search and advertising
• productivity software

This creates a strategic imperative: spend now or become irrelevant later.

Microsoft’s partnership with OpenAI is not just an investment - it is a defensive moat against Google’s Gemini, Amazon’s Anthropic partnership, and Meta’s open‑source strategy.

This is the logic behind strategic dependency.

3. Market Expectations: Investors Tolerate Losses - For Now

Investors understand that frontier AI is a long‑term play. As long as vendors demonstrate:

• rapid adoption
• strong ecosystem growth
• credible monetization pathways
• increasing enterprise integration
• the market will tolerate losses.

But this tolerance is not infinite. If revenue growth stalls or adoption plateaus, investor pressure will force vendors to slow spending.

This is the dynamic of market tolerance.

4. The Real Constraint: Infrastructure Saturation

The biggest limiting factor is not money - it is physical infrastructure.

Datacenters take years to build. Power grids must be upgraded. Supply chains for GPUs and networking fabric are constrained.

Even if vendors wanted to double spending, they often cannot.

This natural bottleneck slows the burn rate and extends sustainability.

This is the core of infrastructure saturation.

5. When Does the Spending Plateau?

Most analysts expect the current hyper‑investment phase to last 3–5 more years, followed by a stabilization period where:

• model training becomes more efficient
• inference costs decline
• monetization improves
• enterprise AI revenue grows
• datacenter expansion reaches maturity

At that point, losses shrink and AI becomes a net contributor rather than a drain.

Conclusion

Microsoft and other vendors can sustain massive AI losses for several years because they have the financial strength, strategic motivation, and investor support to do so. But this spending cannot continue indefinitely. Physical infrastructure limits, competitive pressure, and the need for profitability will eventually force a shift from expansion to optimization.

AI is following the same pattern as cloud computing: a decade of heavy losses, followed by decades of dominance. The companies investing today are not trying to win the next quarter - they are trying to win the next era of computing.

🤖〽️Prompt Engineering: Copilot Unabridged (Part 213: Why Massive AI Investments Generate Massive Losses)

Prompt Engineering Series

Prompt: "write a post of 600 words and explain why the AI investments made by Microsoft and other vendors generate huge losses,. "

Introduction

Artificial Intelligence (AI) has become the defining battleground of modern technology. Microsoft, Google, Amazon, Meta, and others are pouring tens of billions into AI infrastructure, model training, and ecosystem development. Yet despite explosive public interest and rapid enterprise adoption, these companies report staggering short‑term losses tied directly to their AI initiatives.

This paradox - sky‑high investment, sky‑high losses-is not a sign of failure. It is a structural feature of frontier‑scale AI. To understand why, we need to examine the economics behind training large models, the infrastructure required to run them, and the strategic pressures that force vendors to spend aggressively even when profitability is years away.

1. Frontier‑Model Training Costs Are Exponential

Training a frontier model is not a linear expense. Each generation requires more parameters, more training tokens, larger datasets, and more compute cycles. A single training run for a cutting‑edge model can cost hundreds of millions of dollars.

This is why frontier‑model training is the first and most visible driver of losses. Vendors must run multiple training cycles, safety evaluations, fine‑tuning passes, and inference optimizations. Microsoft’s partnership with OpenAI means Azure absorbs the bulk of these compute costs, directly impacting earnings.

2. Infrastructure Build‑Out Is Historically Unprecedented

AI does not run on ordinary cloud servers. Vendors must build:

• GPU superclusters
• High‑bandwidth networking fabrics
• Liquid‑cooling systems
• Specialized datacenters optimized for AI workloads

Each hyperscale datacenter costs $1–$2 billion, and hardware depreciates quickly. Today’s top‑tier GPU becomes mid‑tier in 18–24 months. This creates a cycle of continuous capital expenditure that depresses short‑term profitability.

This is the core of AI infrastructure economics.

3. Inference Costs Scale With Usage

Traditional software has near‑zero marginal cost. AI does not.

Every query to a large model consumes compute, electricity, and cooling. When millions of users interact with Copilot, ChatGPT, Gemini, or Claude, vendors pay for every token generated.

This is why AI inference is a structural loss generator: revenue must grow faster than usage to break even, which rarely happens in early adoption phases.

4. Monetization Is Still Immature

Most users expect AI to be:

• Free
• Unlimited
• Always available

But the cost structure makes that impossible. Vendors experiment with subscriptions, API pricing, enterprise licensing, and usage‑based billing, yet none of these models currently offset the full cost of running frontier AI.

This is the challenge of AI monetization.

5. Competition Forces Overspending

AI is an arms race. No vendor can afford to fall behind. This creates irrational spending patterns:

• Microsoft invests heavily to stay ahead with OpenAI
• Google accelerates Gemini development
• Amazon pours billions into Anthropic
• Meta open‑sources massive models to shape the ecosystem

In an arms race, losses are tolerated because the alternative is losing strategic control of the next computing platform. This is the logic behind competitive overspending.

Conclusion

AI investments generate huge losses because vendors are not selling a finished product—they are building the foundation of a new computing era. Frontier‑scale AI requires unprecedented capital, massive compute, and continuous reinvestment. The losses are not a sign of weakness; they are the cost of securing future dominance in a market that will reshape productivity, cloud infrastructure, search, advertising, and enterprise automation

🤖Prompt Engineering: Challenges (Just the Quotes)

"Another problem that can be confusing is that LLMs seldom put out the same thing twice. [...] Traditional databases are straightforward - you ask for something specific, and you get back exactly what was stored. Search engines work similarly, finding existing information. LLMs work differently. They analyze massive amounts of text data to understand statistical patterns in language. The model processes information through multiple layers, each capturing different aspects - from simple word patterns to complex relationships between ideas." (Jeremy C Morgan, "Coding with AI: Examples in Python", 2025)

"Chain-of-thought prompting is a method that forces LLMs to reason through a series of steps, resulting in more structured, transparent, and precise outputs. The goal is to break down complex tasks into smaller, interconnected subtasks, allowing the LLM to address each subtask in a stepby-step manner. This not only helps the model to 'focus' on specific aspects of the problem, but also encourages it to generate intermediate outputs, making it easier to identify and debug potential issues along the way. Another significant advantage of chain-of-thought prompting is the improved interpretability and transparency of the LLM-generated response. By offering insights into the model’s reasoning process, we, as users, can better understand and qualify how the final output was derived, which promotes trust in the model’s decision-making abilities." (Sinan Ozdemir, "Quick Start Guide to Large Language Models: Strategies and Best Practices for Using ChatGPT and Other LLMs", 2024) 

"AI isn’t just going to be about our digital world. It’s also about our physical world; and applied properly, imagine what AI can do for the pace of discovery and innovation. It’s not just makeup; imagine what it can do for new materials discovery for medicine, energy, climate, and all the other pressing challenges we face as a species - these are the same challenges of makeup, just described with a different 'language'. And quantum computing evolves, we’re bound to see a synergy of these innovations that we can use to tackle these problem domains and more." (Rob Thomas et al, "AI Value Creators: Beyond the Generative AI User Mindset", 2025)

"LLMs can inadvertently produce toxic content or biased language, leak private information, or be vulnerable to jailbreak prompts. These risks carry serious legal and reputational consequences. To mitigate them, evaluation tools must integrate automated filters and classifiers that flag problematic outputs in real time, as we discussed earlier in the chapter. Metrics such as safety scores, toxicity indices, and bias measurements should be collected alongside model metadata for auditing purposes." (Abi Aryan, "LLMOps: Managing Large Language Models in Production", 2025)

"LLM developers can train the model simply to perform well on the benchmarks, like a student memorizing the answers to an upcoming exam. This is a very serious problem in practice. It’s not uncommon to see an LLM perform well in general benchmarks, only to perform below the level of GPT-3.5 (a now-obsolete but inexpensive model) in a practical application, like describing a scene. When this happens, there’s usually little reason to use the model that has the higher general scores - your users should have the final word. Another problem is that LLMs are highly sensitive to the compatibility of the data used in training and prompts used in evaluation. A seemingly minor change in the prompt can lead to drastically different outputs. This makes it difficult to design prompts that consistently elicit the desired response and assess the LLM’s true capabilities." (Abi Aryan, "LLMOps: Managing Large Language Models in Production", 2025)

"The art of mega-prompts spanning multiple written pages and looking like essays has become commonplace for complex tasks when building applications to get things `just right'. Unfortunately, they bring with them lots of issues: errors, portability, complexity, and more. The GenAI world didn’t plan for mega-prompts. They have simply evolved into what they’ve become today because practitioners kept wanting to do more and more complex things, and their only way to express those intents was with a prompt. But step back and look at some of these prompts [...] Lurking just below the surface are a bunch of classical computing concepts like data, programming instructions, control flows, memory, and stora - all the components typically associated with classical computing elements."

"The same difficulties that characterize training deep feedforward networks also apply to RNNs; gradients tend to die out over long distances using traditional activation functions (or explode if the gradients become greater than 1). However, unlike feedforward networks, RNNs aren’t trained with traditional backpropagation, but rather a variant known as Backpropagation through Time (BPTT): the network is unrolled, as before, and backpropagation is used, averaging over errors at each time point (since an 'output', the hidden state, occurs at each step). Also, in the case of RNNs, we run into the problem that the network has a very short memory; it only incorporates information from the most recent unit before the current one and has trouble maintaining long-range context. For applications such as translation, this is clearly a problem, as the interpretation of a word at the end of a sentence may depend on terms near the beginning, not just those directly preceding it."

"When there are hidden layers between the input and output, the problem becomes more complex: when do we change the internal weights to compute the activations that feed into the final output? How do we modify them in relation to the input weights? The insight of the backpropagation technique is that we can use the chain rule from calculus to efficiently compute the derivatives of each parameter of a network with respect to a loss function and, combined with a learning rule, this provides a scalable way to train multilayer networks."

"There is no law of physics tdictates AI must remain expensive. The cost of training and inference isn’t fixed - it is an engineering challenge to solved. Businesses, both incumbents and upstarts, have the ingenuity to push these costs down and make AI more practical and widespread." (Rob Thomas et al, "AI Value Creators: Beyond the Generative AI User Mindset", 2025)

"While the backpropagation procedure provides a way to update interior weights within the network in a principled way, it has several shortcomings that make deep networks difficult to use in practice. One is the problem of vanishing gradients. [...] As the value of the sigmoid function increases or decreases toward the extremes (0 or 1, representing either 'off' or 'on' ), the values of the gradient vanish to near zero. This means that the updates to and , which are products of these gradients from hidden activation functions , shrink toward zero, making the weights change little between iterations and making the parameters of the hidden layer neurons change very slowly during backpropagation. Clearly, one problem here is that the sigmoid function saturates; thus, choosing another nonlinearity might circumvent this problem."

Prompt: "write a post of 600 words on how to use multi‑modal stressors for holistic evaluation in which stress testing reflects the complexity through incomplete or corrupted inputs in AI models"

Introduction

As Artificial Intelligence (AI) systems expand into multi‑modal architectures - processing text, images, audio, diagrams, tables, and code - their vulnerabilities become more complex. Real‑world environments rarely present clean, perfectly aligned inputs. Instead, models must interpret incomplete, corrupted, or partially contradictory signals across modalities. This is where multi‑modal stressors become essential. By deliberately introducing degraded or inconsistent inputs, evaluators can observe how the model prioritizes signals, how it compensates for missing information, and where its reasoning begins to break down.

Incomplete or corrupted inputs matter because each modality activates different representational pathways. Text relies on linguistic priors; images rely on spatial embeddings; audio relies on temporal patterns; code relies on structural logic. When one modality is degraded, the model must decide whether to rely more heavily on the remaining modalities or attempt to reconstruct the missing information. That decision exposes its internal hierarchy of cues, a central theme in instruction‑priority testing.

One of the simplest multi‑modal stressors is the partially corrupted image. For example, an image may be blurred, occluded, or missing key regions, while the accompanying text describes a scene that may or may not match the visible content. This tests whether the model over‑trusts visual fragments or defaults to textual interpretation. The result reveals how the model resolves conflicts between incomplete sensory input and linguistic cues - an essential capability for real‑world robustness.

A more advanced technique involves cross‑signal incompleteness, where each modality is missing different pieces of information. For example:

• The text describes an event but omits the key actor.
• The image shows the actor but hides the action.
• The audio clip provides environmental noise but no speech.

The model must integrate these partial signals to form a coherent interpretation. This exposes whether the model can perform multi‑modal reconstruction, or whether it collapses into hallucination or over‑generalization - patterns often surfaced through weak‑point analysis.

Another powerful stressor is corrupted‑modality contradiction, where the corruption itself creates misleading cues. For example, a distorted audio clip may sound angry even though the text describes a calm conversation. Or a corrupted diagram may misalign labels, contradicting the accompanying explanation. These stressors force the model to determine whether the corruption is noise or signal. The model’s behavior reveals whether it can distinguish reliable from unreliable modalities, a key insight for holistic evaluation.

Incomplete inputs can also be used to test temporal resilience. A video clip may drop frames, skip segments, or freeze mid‑action, while the text describes a continuous sequence. The model must decide whether to trust the visual timeline or the textual narrative. This exposes how the model handles temporal reasoning, a capability often overlooked in single‑modality evaluation.

The most challenging multi‑modal stressors involve hybrid corrupted inputs, where multiple modalities degrade in different ways. For example:

• A table with missing values contradicts a narrative summary.
• A diagram with corrupted labels conflicts with a code snippet.
• An audio clip with static obscures key words while the text misidentifies the speaker.

These hybrid contradictions push the model into conceptual regions where no training example exists. The resulting behavior reveals the model’s cross‑modal arbitration strategy, a crucial insight for understanding its robustness.

Ultimately, multi‑modal stressors that use incomplete or corrupted inputs allow evaluators to move beyond surface‑level robustness. By introducing degradation across text, images, audio, diagrams, and structured data, we can map the deep architecture of model reasoning - how it prioritizes modalities, how it compensates for missing information, and where its internal logic becomes unstable. This is the next frontier of boundary‑stress evaluation: not just testing what the model can do, but testing how it behaves when the world becomes noisy, partial, and imperfect.
